How to get the array values from Array?

October 6, 2022

How to get the array values from JSON. I’m trying to pass it on highchart drilldown data[{}] and need to get the desired outcome in able to display the name and it’s total. Right now, I’m only getting these values 0,1,2,3,4,5,6,7,8,9,10 in my chart.

[
   {
      "course_code":"BSEE",
      "total":1
   },
   {
      "course_code":"BSIT",
      "total":3
   },
   {
      "course_code":"BSME",
      "total":0
   },
   {
      "course_code":"BSOA-LT",
      "total":0
   },
   {
      "course_code":"DICT",
      "total":0
   },
   {
      "course_code":"DOMT",
      "total":0
   }
]

This is my desire outcome

[
   {
      "BSEE",
      1
   },
   {
      "BSIT",
      3
   },
   {
      "BSME",
      0
   },
   {
      "BSOA-LT",
      0
   },
   {
      "DICT",
      0
   },
   {
      "DOMT",
      0
   }
]

>Solution :

Array.map approach

const data = [
  { course_code: "BSEE", total: 1 },
  { course_code: "BSIT", total: 3 },
  { course_code: "BSME", total: 0 },
  { course_code: "BSOA-LT", total: 0 },
  { course_code: "DICT", total: 0 },
  { course_code: "DOMT", total: 0 },
];
const output = data.map(({ course_code, total }) => [course_code, total]);
console.log(output);
